JEAN GAY DE TREZ, OF GENEVA, SWITZERLAND.

HEEL FOR BOOTS AND SHOES.

SPECIFICATION forming part of Letters Patent No. 264,029, datedSeptember 5, 1882,

Application filed March 13, 1882. (No model.)

to injure the flooring or carpets, or to slip on stone or on iron.

In the drawings, Figure 1 shows the section of a shoe-heel provided withmy trimming, and an inverted plan of the same. Figs. 2, 3, and 4 showthe three pieces A, B, and O which make up my trimming; and Fig. 5represents a key, the use of which is explained farther on.

The ring A is of metal, either tempered or untempered steel, yellowbrass, 850. It is beveled inside and out, and provided with corrugationsor fine teeth on its surface to prevent the same becoming smooth andslippery. It is, moreover, provided with a circular grooving, thepurpose of which is to cause the surface of the ring next the leather ofthe heel to embed itself into such leather.

The ring A-such as I have described-is placed under the heel in themanner shown in Fig. 1. It is secured by means of the beveled washer B,made of caoutchouc, leather, or any similar material within the ring,and by the metallic piece 0, which is outside of the ring, and providedat its half-circular part with a bevelin g edge corresponding with theoutside edge of the ring A. These two pieces B and O are secured to theheel by means of common tacks and screws.

. The ring Ais provided with twolittle holes, a and b, which areintended to receive the pins a and b of the key D, Fig. 5. By means ofthis key it is easy .to partially turn the ring A. By repeating thisoperation from time to time the metallic part of the heel will wearequally all around it everywhere.

The holes a and b in the ring A may be replaced by a notch forpermitting the ring A'to be turned by any suitable instrument.

I claim as my invention- In combination with the plate 0 and disk B,permanently attached to the heel, the ring A, beveled on its outer andinner edges, so as to be held by the disk B and plate 0, and having aroughened exterior surface and grooved upon its upper surface, so thatthe ring embeds itself into the leather, substantially as set forth.
